An Interview with Wes Colley YL: What are the most important factors in rating sports teams? Wes: For the more typical team sports, such as football and basketball, you can try to use score or something, or even secondary stats such as scoring defense, but I tend to believe that winning is the name of the game, and therefore stick with wins and losses as the basis of my system. Wins and losses alone work very well for rating professional teams, because the number of games is large (relative to the number of teams), and the level of the teams is quite similar. In college sports, those two criteria are not nearly met, and a strength of schedule component MUST be added. YL: Do you have any plans to rate the NFL this way? YL: Do you think the Strength of Schedule component is a bit overplayed since ratings and rankings already include them and the polls certainly consider how strong team's opponents are? Wes: The strength of schedule "column" was removed from the BCS for the 2004 season. The system was simply (AP+Coaches+[Computer Avg.])/3. It's slightly more complicated than that, but that's the idea. No "tweak" columns were in place. YL: I guess I lost track of what the BCS was doing. They actually did something to improve it and it went right past me. I guess I've gotten to the point where I try to ignore them. Now I'll have to watch them again. Season before last, people blamed the ratings. Last season the redundant schedule strength was removed and they blamed the polls. See how much better it is? Wes: The AP pulled out, via a strange cease-and-desist letter to the
BCS that says, essentially, "in order for us to complain about the BCS with
impunity, please remove our rankings from the BCS." So now you're
down to the coaches and computers. I think the BCS folks meet this month,
so we'll see what happens. YL: I guess we'll never all be happy until they all have to play each other. Is your system predictive or retrodictive? Wes: Well, retrodictive. I've used the words "it hindcasts rather than forecasts," but "retrodictive" is okay. YL: Retrodictive has somehow become the chosen term - I once read that the guy who introduced it to sports ratings used it because he couldn't come up with a better term at the moment. When and why did you begin to rate teams? Wes: When and why: When: 1998, the first year of the BCS. Why: a very strong interest in college football... In 1998 when the BCS came around, I thought most of the computer rankings were unnecessarily complicated and clouded in mystery, so I decided to create a simple, open system, which people could understand and check. I particularly wanted one with no conference weighting factors, or pre-season information. I'm delighted that some people have gone to the trouble of checking my system and verifying its results. YL: What is the future of computer ratings and the BCS? Wes: Good question. I basically have no idea. Every year there seems to be some misplaced pre-bowl outrage, then some hindsight post-bowl outrage, frequently mutually exclusive to the former, but at the end of the day, agreement that the correct national champion was crowned. As long as that's the case, I doubt the BCS will go away. YL: Do you have favorite teams or sports? Wes: I'm an alumnus of UVa, so it's not surprising that UVa is my favorite team. I go to all the home football games and usually an away game or two. I also follow UGa football very closely. My brother played football there, so my family naturally became involved with UGa football. YL: I really like the concept of your system. I developed practically the same thing once and I thought it was great. Then one day Todd Beck sent me an email and said my ratings were in the BCS. It was then that I discovered that my great, new concept wasn't new, after all. I know from my own almost-identical system that a good team beating a lousy team seems to be penalized and a lousy team losing to a good team seems to get rewarded. Do you use Strength of Schedule to counteract that or do you think that good teams should play good teams? Also, do you think, as I do, that using your rating system as the standard would push teams into playing more logical opponents so that they could get a better rating, thereby earning their position? Wes: It's true that if an already good team beats an already lousy
team that the good team may suffer a small ratings decline and the lousy team
may receive a small ratings bump. However, there are two important things
to keep in mind here: YL: We can see that you are very thoughtful and analytical about ranking teams. Is this something we would see in your profession? What keeps you busy when you're not ranking teams? Wes: I am a senior research scientist at the Virginia Modeling Analysis and Simulation Center of Old Dominion University, where I work mainly on Department of Defense and Department of Homeland Security research. YL: Where do you call home? Wes: The Hampton-Roads area of Virginia. YL: What else can we get you to tell us about Wes Colley? |
Go to the Speaking Out In my lifetime we have gone from politeness and common sense to political correctness. Ironically, the same people that want to organize manners want to de-organize religion. In other words, they are very confused. I am tired of the 85+ % liberal press and radical college professors putting crap into young people's heads. Here are some places and articles where you can hear common sense which is not regulated. Where to get real news from both sides. What a concept. Articles Gee, I wonder how young Arabs learn to hate Israel? If you don't get it yet, they are taught to hate in many places. Here's an example. What Do You Want Israel to Do? You Solve the Problem. What is the real goal of Arabs and "Palestininas"? Liberal politicians in general just do not get it. Just Another Group Promoting Racism and Hatred Someone is Defending our Freedom of Speech. CAIR is not my friend. If you like freedom of speech, CAIR is not your friend and they're spending your tax dollars in a deliberate lie. The Dishonest Reporting Awards are Out! I thought universities were "enlightened" and open-minded. Seems they are only open-minded to those with whom they agree. "Enlightened"? How about "in the dark"? Deconstructing the False Equation There is no apartheid in Israel. Deal with it. Common Sense Sources Media Myths Explained. Think you're getting accurate news about what's going on in the Middle East? If You Want to Use your Brain Instead of Being a Parrot, Research Both of These Sources: Since the hippies tried to save the world, every new generation thinks it has the solution to all the problems the current leaders have caused. It takes a long time to civilize a society. It doesn't take long for "idealists" to destroy it. I am conservative. I believe that our values and ideas should continue unless they are proved to be inferior over time. I do not like the liberal concept of trashing things that work and replacing them with things that sound good. Study both sides to find out what is true. Stop telling me I am a racist and hateful and more unless you have studied my side's viewpoint. I do not like watching the media cause problems so they can sell papers and airtime the next day while blaming those problems on the other side. Wise up. |
